Abstract

The purpose of the present work was to study variations of certain properties of glasses, from which it might be possible to draw inferences regarding their structure and structural changes occurring during heat treatment near the softening temperature for various times. Variations of the properties of glasses during heat treatment at low temperatures have been studied by many workers. It has been shown [1, 2] that changes of glass properties during heat treatment in the vitrification region are due to structural transformations. Others correlate changes of mechanical properties with the location of the glass composition on the phase diagram [3]. De-mishev [4] showed that displacement and slippage of structural complexes in glass may occur at the vitrification temperature.
